SPECIFICATION forming part e'f Letters Patent No. 655,648, dated August 7, 1900.

Application led March 21, 1900.

To all whom t may concern:

3e it known that we, VILLIAM H. BAKER, residing at Central Falls, Providence county, Rhode Island, and FREDERIC E. KIP, residing at Montclair, Essex county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to looms having means for replenishing weft or filling automatically, and particularly to what are known as double-shuttle looms, wherein two shut tles, one above the other, are picked simultaneously through the sheds in the warps.

According to the present invention two shuttle-boxes are superposed and open at the sides, and the shuttles are also open at the sides instead of at top and bottom. The weftcases or weft-holders, such as bobbins or bobbins in bobbin-cases, are mounted detachably in an upright endless chain carrier which constitutes a magazine and are brought in front of the shuttles in the shuttleboxes, drivers being employed to drive full weftholders laterally vfrom the chain-carrier of the magazine or holder into the shuttles as required, means for operating said drivers being controlled by the presence or absence of weft or filling on the weft-holders in the respective shuttles.

In the accompanying drawings, which illustrate the invention, Figure l is a side elevation of a part of the loom illustrating the invention, and Fig. 2 is a front elevation of the same. Fig. 3 is a sectional elevation, on a larger scale, illustrating the construction of the magazine, shuttle-boxes, and adjacent parts. Fig. 4 is a section at the axial lineA in Fig. 8. Fig. 5 is a detail view of the chainguide, showing the guide and chain in horizontal section on a relatively-large scale. Fig. G is a vertical longitudinal section of a shuttle-box, showing the shuttle therein in side elevation. Fig. 7 is a horizontal axial section of the shuttle. Fig. 8 is a front face view of the shuttle-boxes and lay, illustrating the electricalconneetions. Figs. 9, l0, 11, and l2 illustrate a mechanical controlling device with an automatic feeler, which device may be substituted for the electrical controlling device of the principal views.

c, represents the loom frame. Z) is the breast-beam forming a part thereof. c is the lay, which may be provided with two raceways c c2, as shown in Fig. 8. d shows the 6o lay-swords. e is the picker-stick, and f is the shaft from which the lay receives its vibrations through cranks and connecting-rods in the'usual way. These parts are all common in looms and may be of the usual kind.

` On the lay are mounted the two shuttleboxes g g, open at the sides and provided eachV with a swell h at its top, as seen in Fig. 6. There will be of course a pair of superposed shuttle-boxes at each side' of the loom; but 7o only the pair at the side where the shuttles are supplied is herein shown. The boxes in this pair are alike and are distinguished onlyV by g designating the upper box and g the lower. In these boxes are the shuttles t', 7 5 which are also alike. Each shuttle is open at its sides, so that an exhausted weft-holder therein may be ldriven out at one side by a full weft-holder entering at the other side. On the loomframe is mounted in suitable 8o bracket-supports j the magazine to contain the weft-holders. This magazine is designated as a whole by IVI, and it consists, essen tially, of an upper pair of sprocket-wheels le, a lower pair of sprocket-wheels 7c', and an end- 8 5 less-chain carrier Z, mounted on said sprocketwheels and provided with spring-clips m to hold in place the weft-holders. In the drawings this weft-holder is a metal bobbin-case n, containing a bobbin o, as seen best in Figs. 9o 6 and 7. The chain-carrier of the magazine is advanced step by step to bring the weftholders as needed opposite to the shuttles in the shuttle-boxes, the movement being, as herein shown, upward at Ithe delivery side of 95 the carrier next to the shuttle-boxes. The movement ot" the carrier is effected through the medium of a slip-belt p, driven by a pulley q on the crank-shaft f of the loom, said belt passing about a pulley r, Fig. 4, loose on roo the boss of the upper pair of sprocketwheels 7c, being connected to said boss through a spring s, which is wound or put under tension by the belt p, workin gfrictionally on the pulley r. lVhen the chain-carrier is restrained bya detent, (to be described,) the beltp winds up the springs until the tension thereot` overcomes the friction of the belt, when the latter slips. A specific device of this character for constantly tending to rotate a magazine containing weft is illustrated in our pending application, Serial No. 4,221, filed February 6, 1900, and is not specifically claimed herein.

A detent device holds the chain carrier against movement until a weft holder is driven therefrom into the shuttle and then permits the carrier to advance to the extent ofjone weft-holder, so that the next weftholder in succession takes the place of that displaced. The preferred form of detent t is best illustrated in Figs. 3 and 4. It is in the nature of a rocker pivotally mounted on the bracket supporting the magazine and having two arms which take over from behind the two bobbin-cases that occupy positions at the delivery-point. So long as both of these bobbin-cases are in position in the chain-carrier the latter is held against movement; but if either bobbin-case be displaced the detent is free to rock and allow the other bobbin-case to wipe past; but as the next succeeding' bobbin-case comes into position the two will wipe intotheir places in the detent and lock the chain against further movement. For example, if the upper bobbin-case be driven into the upper shuttle the chain-carrier will move up to the extent of one bobbin-case; but if the lower of the two bobbin-cases be driven into the lower shuttle the chain-carrier Will move up to the extent of two bobbincases. The extent of movement of the rocking detent t is limited by an arm on the back thereof playing between two studs on the supporting-bracket. This arm is sufticiently indicated by dotted lines at u in Fig. 3.

The means for driving the weft-holders into the respective upper and lower shuttles are the drivers 'U and @which are pivotally mounted at w on the loom-frame. These hammers are actuated by the lay in beating up through the medium of a dagger or tappet so thereon. The drivers are situated side by side, and to them below the common pivot or fulcruni w are coupled or hinged, respectively, arms g/ andy', which rest, respectively, on the armature-levers of two electromagnets z and a'. The drivers are held drawn back normally by any form of springs 1, and the usual springs uphold and retract the armature-levers of the electromagnets normally. Vhile the armature-levers are thus upheld the arms y and y are elevated and held above the path of the tappet an; but if either magnet be excited it will attract its armature, draw down its lever, and thus permit the arm y ery', which it supports, to descend into the path of the tappet x, so that when the loom beats up the driver coupled to that arm will be actuated. Figs. 1 and 4 show the lay beat up under normal conditions or when no fresh supply of weft is required.

The means whereby the excitation of either 7o of the electromagnets is controlled by the substantial absence of weft on the shuttle in play may be effected in any known way. We have illustrated herein, Fig. 7, the construction for this purpose which is shown and claimed in our pending application, Serial No. 411, fled/ January 5, 1900, and this construction willy now be briefly described, premising, however, that as each shuttle, shuttle-box, bobbin-case, dac., is fitted up in the same manner a descrip- 8o tion of one of each will suffice for all, and premising also that the electrical devices employed are substantially duplicated, one for the upper box and one for the lower. Reference may be had especially to Figs. 6, 7, and 8.

The bobbin-case n is of metal, preferably (but not necessarily) cylindrical and in two sections telescoping and insulated from each other at 2. This case is held in the shuttle c' by metal spring-jaws 3 in the shuttle at each end of the cavity therein. ln the bobbincase is hinged a metal spindle 4 to receive the bobbin o. On this spindle is a spring 5 and a metal washer 6, which is electrically connected by suitable conductors with a metal plate 7 in the bottom of the shuttle at lthat end. At the other end of the shuttle the spring-jaws 3 are electrically connected with a similar metal plate 7. When the shuttle enters its box, the respective plates 7 and 7 are put into contact with terminals 8 8a, Fig. G, of an electric circuit, including conductors 9, a generator 9a, and one of the electromagnets e or e. Fig. 8 is a diagrammatical view showing the two circuits.

The bobbin o, which may be of wood, has at its end a metal ring or piece 10, which is in contact with the washer 6 on the spindle, and from this ring 1O projects a spring 11, which takes under and presses outward radially a metal indicator 12, hinged in a slot in the bobbin, with its free end adapted to be pressed into contact by the spring 11, with the inner surface of a flanged outer metal ring 13 on the bobbin. The weft or iilling on the bobbin overwraps an arched portion of the indicator 12, however, and holds its free end out of contact with the ring 13 normally. When the bobbin is slipped onto the spindle, the iiange on the ring 13 talles over and is in electrical contact with a spring-hlade 14 on the right-hand section of the bobbin-case as the construction is illustrated in Fig. 7. It will be seen Without further description that when the shuttle enters its box the circuit will always be completed, except between the indicator 12 and the ring 13, and that when the weft or iilling on the bobbin shall have become nearly exhausted the spring 11 will be permitted to press the indicator 12 out into contact with the ring 13, so that when the shuttle next enters the box at the same side of the loom as the magazine the`V IOO and the arm circuit will be completed through the magnet y or y lowered into the path of the tappet Consequently when the lay beats up the driver will drive a fresh bobbincase into the shuttle and expel the exhausted one therefrom.

On the bobbin-cases n and near the ends of the same are placedcushions or padsnl, of rubber or other soft material, to cushion the blow of one case on the other, and each case will have a hole 16 in its side to lead out the weft end. The magazine will have a suitable weft-end holder which moves with the carrier, and this may be constructed as best seen in Figs. l, 2, and 4. A shaft 17 is mounted rotatively in the bracket j, centrally between the axes of the sprocket-Wheels, and geared to. the upper sprocket-wheel shaft for driving by sheaves 18 and 19 and a belt 20. On the outerV end of this shaft is the weft-end holder 21, to which the weft ends are led out and attached. The sheaves 18 and 19 are properly proportioned to give to the holder 2l the proper speed.

In order to keep the erly alined at the delivery-point and to provide a resistance for the blows of the drivers, there are iixed upright guides 22, carried by the bracketor brackets supporting the magazine. Fig. 5 shows one of these guides 22 in detail.

It will be understood that while we have shown electrical controlling devices similar to that shown in our before-mentioned pending application we do not limit ourselves in this respect. We may employ mechanical controlling means including a feeler-for example, such as that illustrated in our pending application, Serial No. 4,221, filed Feb-v ruary 6, 1900.

ln Figs. 9, 10, 11, and 12 we have illustrated the adaptation of the feeler device of our copending application, Serial No. 4,221, to a double-shuttle loom, and this device will now be described. Mounted in bearings on the face of the lay are two rock-shafts 23 and 23a,

one being tubular and the other passingy through it. On each shaft is a pair of lugs 24, in which is hinged a tappet 25, supported somewhat elastically by a spring-blade 26. By rocking either of said shafts the tappet 25 carried thereby maybe put in position, so

that when the lay beats up said tappet will impinge upon a toe UX on the opposite driver. There are two of these toes situated side by side, and each tappet is adapted to strike one ot' the toes. 23 and 23L are crank-arms 27 iand 27a, from which extend upward connecting rods or links 28 and 28, coupled at their upper ends to crank-arms 29 and 29n on two rock-shafts 30 and 30 on the sides of the respective superposerl shuttle-boxes. As each box is fitted u p in the same way it will only be necessary to describe one, with especial reference to Fig. l1. The rockshaft 30 has on it an arm 31, which loosely engages a feeler-lever 32,

chain-carrier Z prop` On thev respective rock-shafts adapted to swing about a pivot on the lay.- The curved free end of the feeler-lever is adapted to enter the shuttle-box and the shuttle therein. A spring 33 on the shaft tends so to rock the latter as to cause the feeler to enter into the shuttle and box and also to elevate the tappet 25 through the connecting-link. When the lay swings back or recedes to the picking and receiving position, the lower rock-shaft is rocked, so as to withdraw the feeler from the shuttle and box, and this is effected by means of a fixed dagger q on the loom-frame, which impinges on arms 34: on the respective rocksliafts 23 and 23a. On the lower side of the shuttle, Figs. 11 and 12, is pivotally mounted a feeler-tinger 35, which is in the path of the feelerdever. A spring 36 on the shuttle bears on the shorter arm of the linger 35 and holds the longer arm of the latter pressedy up to a stop 37, as seen the shuttle, under the weft-holder 'm' therein, so that if the indicator 12 in the latter be protruded the finger will impinge thereupon and be limited in its movement thereby, as explained in our said application. tion is precisely the same as illustrated in our said copending application, and the stationary dagger g for withdrawing the feelertion.

, In lieu of employing bobbin-cases containing bobbins we may mount the bobbins themselves directlyin the spring-clips in the magazine, in which case self-threading shuttles, such as are now known in the art, would be employed. We have not deemedit necessary to illustrate these departures from the con'- struction illustrated, as they will be obvious to any one skilledin the art to which this invention pertains. I

We are aware that double-shuttle. looms supplying from twoseparate magazines full shuttles to the raceway are not new; but as we' are the first, as we believe, to supply a weft-holder containing afresh supply of weft or illing into either or both of the active shuttles as they require to be replenished with said weft or illing during the same pick of the loom and also to supply weft for both sheds from a single magazine we claim same broadly and do not limit ourselves to any specitic construction for accomplishing this result, as same may be varied considerably. We would consider our invention practiced in a double-shuttle loom havingweft or filling supplying, mechanism wherein 'weft or lling is supplied from a single magazine to one or both of the warpsheds,.as required, during the Weaving.

By weft-holder or bobbin as herein expressed is meant any known device on which weft or filling is wound, and by weftcase or bobbin-case as herein expressed shuttle containing weft or iilling.

in Fig. 12, normally; butwhen the i'eeler-lever strikes said finger it swings the latter into' is meant any receptacle adapted to go into a' The opera- (lever will be the same as in the said applica- IOO,
